Dynamic analysis of sandwich magnetostrictive nanoplates with a mass-spring-damper stimulator

Present study investigates the dynamic behavior of a three-layered composite nano-plate with an attached nano mass-spring-damper system. The composite constitutes of three layers so that the core is made from magnetostrictive material, whereas, facesheets are supposed to be from a functionally graded material (FGM). Additionally, the proposed system is supposed to be rested on visco-Pasternak foundation. Governing equations of the nano-plate are derived based on higher-order shear deformation theory (HSDT) and Hamilton’s principle. Navier’s solution and Laplace transform are applied to solve partial and ordinary differential equations, respectively. Thereafter, a comprehensive study is carried out whose concentration is on investigation of the influence of different parameters on the dynamic response of the continuous system. The results indicate that adding the mass-spring-damper system to the nano-plate significantly affects the natural frequency. The outcomes can be used as benchmarks for efficient design of nano-sensors, nano-resonators, and drug delivery systems.
